In a second example, the fastener 50 (150, 250, 350, 450, 550) is fixed to an element different from thebicycle 10. - The subject fixed by the fastener 50 (150, 250, 350, 450, 550) can be changed to any subject. In a first example, the fastener 50 (150, 250, 350, 450, 550) fixes an element that is mountable on the
bicycle 10 and different from thebottle cage 80 to thebicycle frame 12. In a second example, the fastener 50 (150, 250, 350, 450, 550) is used just to perform wiring with thelinear member 42. In the first and second examples, thebicycle 10 can have a configuration in which thebottle cage 80 is omitted. - The basic structure of the fastener 50 (150, 250, 350, 450, 550) can be changed to any structure. In a first example, the basic structure of the fastener 50 (150, 250, 350, 450, 550) is a rivet. In a second example, the basic structure of the fastener 50 (150, 250, 350, 450, 550) is a press-fitting pin. In a third example, the basic structure of the fastener 50 (150, 250, 350, 450, 550) is a set screw. In the first to third examples, the relationship between the first maximum width WA1 and the second maximum width WA2 is accordingly changed.
- The configuration of the
intermediate member 44 can be changed to any configuration. In a first example, with the fastener 50 (150, 250, 350, 450, 550) engaged with thebicycle frame 12, theintermediate member 44 is located between the head 52 (152, 252) and thebottle cage 80. In a second example, with the fastener 50 (150, 250, 350, 450, 550) engaged with thebicycle frame 12, theintermediate member 44 includes a first intermediate member located between thebottle cage 80 and thedown tube 12C and a second intermediate member located between the head 52 (152, 252) and thebottle cage 80. - The configuration of the
linear member 42 can be changed to any configuration. In one example, thelinear member 42 includes a wire such as a Bowden cable. - The
bicycle 10 can have a configuration in which thewireless communication portion 82 is omitted. In one example, thelinear member 42 is arranged to extend through the fastener 50 (150, 250, 350, 450, 550) to electrically connect theoperation device 38 and thejunction unit 84 in a direct manner. - 12) bicycle frame, 12C) down tube, 12D) seat tube, 40) wiring assembly, 42) linear member, 42A) wire, 44) intermediate member, 48A) first electric terminal, 48B) second electric terminal, 50) fastener, 52) head, 52A) first end, 52B) second end, 54) first inner peripheral surface, 54A) first through hole, 56) groove, 58) first outer peripheral surface, 58A) tool engagement portion, 60) first opening, 60A) edge, 62) first curved surface, 64) second opening, 64A) edge, 66) second curved surface, 70) shank, 70A) third end, 70B) fourth end, 72) second inner peripheral surface, 72A) second through hole, 74) second outer peripheral surface, 74A) engagement portion, 74B) threaded portion, 76) third opening, 76A) edge, 78) third curved surface, 80) bottle cage, 82) wireless communication portion, 94) additional groove, 150) fastener, 152) head, 152A) first end, 152B) second end, 154) first inner peripheral surface, 154A) first through hole, 250) fastener, 252) head, 252A) first end, 252B) second end, 254) first inner peripheral surface, 254A) first through hole, 258) first outer peripheral surface, 350) fastener, 450) fastener, 550) fastener, WA1) first maximum width, WA2) second maximum width
